Title: Improvements in or relating to the production of metal oxides
Inventor: NUTTING ROBERT DANA
IPC: C01G23/07
Filed: 1954-02-08
Abstract: In the decomposition of a vaporized metal chloride, bromide or iodide with an oxidizing gas to form the corresponding oxide, the decomposition is effected within a reaction zone provided with a porous refractory wall which is cooled and maintained free from scale on the inside thereof by forcing a normally gaseous fluid in the liquid state, which is inert towards the reactants and the reaction products under the reaction conditions, into and through the wall for vaporization on the surfaces thereof.  An examplary apparatus is shown in the Figure wherein an oxygen containing gas is fed through line 4 to flow through a vertical pipe 3, and titanium tetrachloride, for example, to be decomposed is fed from line 10 to a chamber 12 surrounding the tube 3 and <PICT:0764083/III/1> from which the titanium tetrachloride enters the oxygen flowing through the tube 3 through a slotted jet 13.  The reactant inlets are contained in a furnace 1 which may be heated or insulated. The mixture of reactants passes into the main reactor 6 which is provided with porous walls 7 about which is a jacket 15 to which the liquid shielding fluid is fed; the reaction products are removed at 5.  The porous wall may be made of aluminium oxide, zirconium dioxide, porous carbon or graphite, porcelain, silica, or porous metals such as nickel, steel, platinum or tantalum having in preference a pore diameter of less than 250 microns. Suitable shielding fluids are liquid chlorine, nitrogen, carbon dioxide and carbonyl chloride.  Metal oxides which may be formed include those of iron, titanium, silicon and aluminium the chlorides, bromides or iodides of which are reacted with oxygen, air preferably humidified or steam.  According to a typical example titanium tetrachloride pre-heated to 1000 DEG C. and oxygen at the same temperature containing added water vapour are reacted at approximately 1300 DEG C. and liquid chlorine is passed through the porous reactor wall thereby maintaining the wall temperature not higher than 300 DEG C.  The preferred retention time for the titanium dioxide formed is from 0.1 to 5 seconds.  If desired only the upper portion of the reaction space 6, where scale decomposition is likely to be most, may be made of porous material and the lower section made of solid nickel for example, surrounded by a cooling jacket.  In addition the reactor inlet jets may be formed of porous refractory material and the normally gaseous fluid in the liquid state may be flowed or diffused through these surfaces in order to prevent scale decomposition.  Specifications 757,703 and 764,082 are referred to.

Filed: 1975-01-29
Abstract: 1497292 Measuring angular speed and position electrically UNION SPECIAL GmbH 29 Jan 1975 [30 Jan 1974] 3830/75 Heading G1N The angular speed of the main shaft of a sewing machine is measured by a tachometer comprising a wheel on the shaft, carrying a series of North and South magnetic poles past a Hall plate device, the resulting pulse train being fed through a pulse shaper to be converted to a corresponding voltage representing the angular speed. The series of magnetic poles on the wheel has one North pole and one South pole missing at predetermined angular positions. The shaped pulse train is also fed to a logic circuit Fig. 3 (not shown) which produces control pulses coincident with the pole gaps, to be used e.g. to stop the sewing machine when the needle is in predetermined positions.

Title: Electric control system for circular looms
IPC: D03D37/00
Filed: 1947-02-10
Abstract: 621,008. Loom drives; automatic stop-motions. FAYOLLE, M. Feb. 10, 1947, No. 3863. Convention date. Oct. 3, 1946. [Class 142 (i)] [Also in Group XXIV] An automatic stop mechanism for a circular loom comprises an electro-magnet 1, energization of which engages the main driving clutch 20, Fig. 3, and simultaneously releases a brake 22 against spring resistance 3, the energizing circuit including a series .resistor 4, Fig. 2, such as to reduce the magnet current to a value sufficient only to maintain the armature 2 attracted, but insufficient to attract it from the fully released position, which requires a current increase obtained by temporarily shortcircuiting the resistor 4 by a starting button M. During running the starting switch M remains open, and the magnet is energized weakly through the . resistor 4, so that a momentary interruption of the current by automatic stop mechanisms, or by a push-button A, causes, declutching. The clutchbrake magnet 1 is energized through a relay 5, and the automatic stop mechanisms comprise (a) contacts 8 (in series with the clutch-brake magnet 1) opened when a shuttle 7 becomes disconnected from its driver 6, and (b) contacts C (in series with the relay 5) closed by breakage of a thread. Release of the clutch-brake magnet armature 2 also opens a contact 10 releasing the starter 11 of the main driving motor 12 which thus stops automatically on declutching. In the clutch-brake combination shown in Fig. 3, energization of .the winding 1 attracts directly, or through a lever, the non-rotary armature 2 against spring-resistance 3, drawing it away from an axiallyfixed brake disc 22, fast on a driven shaft 18, and a screw-adjustable abutment 25 on the armature 2 simultaneously releases an internal clutch-withdrawal rod 26, allowing a spring 19 to press a freely-mounted driving pulley 15 axially into clutch-engagement with an axially-fixed clutch-cone 20 fast on the driven shaft 18.

Title: Improvements in or relating to the manufacture of micaceous insulating material
Inventor: WEDLOCK ALBERT WILLIAM HENRY
IPC: H01B3/04
Filed: 1953-02-16
Abstract: Relates to the manufacture of micaceous insulating materials and consists in forming a mixture of (a) ground previously formed micaceous insulating material, (b) ground white glass frit and (c) ground muscovite mica in which mixture the ground micaceous insulating material forms the major proportion, in cold pressing the material into billets, in drying the billets, in subjecting the dried billets to a gradual rise of temperature in a furnace and in pressing in sheet form or moulding to a required shape the heat treated material.  Suitable proportions for the mixture are (a) 60.5 per cent, (b) 9.25 per cent, (c) 30.25 per cent.  Before mixing, the materials are ground till they can pass a mesh of 100 x 100 per sq. in., and during mixing 5-10 per cent of water is added, according to the degree of atmospheric humidity, to act as a binder in the cold pressing stage.  The ingredient (a) is prepared as disclosed in Specification 532,824 which describes a process which consists in mixing ground mica with ground ceramic materials, in cold pressing the mixture, in drying the pressed sheets or blocks before heating, in subjecting the dried sheets or blocks to a gradual rise in temperature in a furnace and in cooling or moulding the heat treated material.  The ingredient (b) is formed during the initial stage of manufacturing (a) and its preparation is also described in Specification 532,824.  The ingredient (b) also provides the ceramic element in the mixture from which the ingredient (a) is formed, the ingredient (a), after the heat treatment, being composed of mica; cryolite; potassium, barium and sodium compounds; borates and volatile matter in stated proportions.  The drying and heating of the billets are conducted as described in Specification 532,824. Products of the invention have useful applications as circuit-breaker arc shields, especially if sheet iron in the shape of an arc shield is introduced at the cold pressing stage, when it adheres to the material.  If about 10 per cent of a kaolin product is added to the composition its heat resistance is increased, at some expense in mechanical strength, and the material is suitable for element winding.
